Application ala August 3o, i919. seriai No. :326384.

To all tf1/wm t may concern:

Be it known that we, F RANKLIN T. SPEN- CER, ARMEE JAursoN, and CLAUDEGr. JAMI- soN, citizens of the United States, residing at Painted Post7county of Steuben, and State of New York, have invented certain new anduseful Improvements in Hotfir Heaters, of which the following is aspeciication.

This invention relates t'o a hot air radiator, particularly designed foruse in connection with gas, oil, stoves or Chot plates and an object ofthe invention is to provide a radiator which is simple in Construction,durable, and may be manufactured for a small cost, and is adapted torest upon the stove for receiving the products of combi'istion risingfrom the burners thereof, and conserving them, permitting the` heattherefrom to radiate through the radiator structure for heating thesurrounding atmosphere.

- Another object of this invention is to provide a hot air radiator asspecified, which is constructed of sheet metal, and has a bafflepositioned therein, intermediate its top and bottom which baffle iseither substan tially conical or pyramidal in shape, having its undersurface hollow, forming a pocket for receiving the products ofcombustion arising from the burners of the stove, and retaining themtherein until they are completely consumed, and also permitting theutilization of the maximum heating effect of the fuel employed inconnection with the stove.

Other objects of the invention will appear in the following detaileddescription taken in connection with the accompanying drawing, forming apart of this application, and in which drawing:

Figure 1 is a vertical section through the improved hot air radiatorshowing the same mounted upon a two burner gas stove.

Figure 2 is a top plan of the hot air radiator.

Figure 3 is a cross section taken on the line 3 3 of Figure 2.

Figure 4 is a top plan of a modified form of the hot air radiator, and

Figure 5 is a vertical section taken on the line 5-5 of Figure 4.

Referring more particularly to the drawing, the improved hot airradiator 10 is illustrated in Figure loof the drawing as mounted upon anordinary two burner gas stove,

of the hot plate type. 'l-lowever, it is 'to be understood that theradiator maybe used in connection with any approved type of gas orl oilstove, without departing from the spirit .of this invention. Theradiator 10 comprises a body 11 constructed of sheet metal, andpreferably rectangular in shape, depending' upon the type of stove uponwhich it is to be used. The lower edges of the body 11 are inturned, asshown at .127 forming va support, which rests upon the top of the stoveA, for supporting the body` 11 over the burners B, of the stove A. 'Theends of the body 11 have handles 13 attached thereto to facilitate theplacing of the radiatr upon or the removing of it from a stove. Adetachable lcover 14 is mounted upon the upper end bf the body 10, andhas a 'depending annular flange which overlaps the upper edgeV 'of thebody. The cover 14 is provided with a plurality of longitudinally andlaterally spaced openings, 15, which are adapted to permit of the escapeof products of combustion from the burners B of the stove therethrough.Suitable sheet metal brackets 17 are provided on the walls of said body11. Each of said brackets comprises a portion lying` parallel upon, andsecured in any approved manner to the inner surface of the body 11; anda portion bent at an acute angle to said secured portion and spaced fromthe side of said body 11. A baflie 16 is secured to the under surface ofthe outwardly bent portion of the brackets 17. The baffle 16 issubstantially pyramidal in shape, being constructed of sheet metal andproviding an elongatedv pocket opening downwardly, which receives theproducts of combustion as they rise from the burners B and retains themtherein until they are completely burned, thereby eliminating` thepassage of any odors from the stove A into the room or atmospheresurrounding the improved radiator struct-ure, and also permitting of theutilization of the maximum heating effect of the fuel of the stove. Itwill. be noted by particular reference to Figures 1 and 3 of thedrawing, that the edges of the baffle 16 are spaced from the innersurface of the sides and ends of the body 11 thereby providing rspace topermit the heated air to rise in the radiator structure above the bafflemember 1G. Due to the fact that no obstructing parts are positioned inthe heater above the bafie miv plate; and 'li rewise due to the Yupwardtapering outer surface of the baffle 16 Vaspace is provided above thebaflle 16, which gradually increases in area upwardly from the lowerinarginaledg'es ot' said balllevl, Yto provide a space lor expandingheat and whereby a draftinay quickly be effectedv through the radiatorstructure.

In Figures 4t and 5 ofthedrawing, a modified forni of the' hotfairradiator struc'.-

ture is shown, this ormrbeing adapted forv lindrical body 20. AThiscover 23 is provided with a depending flange 24: which overlaps theupper edge of the body and is alsovprovided.

with a plurality ol perforations 25 extending therethrough to permitventilation of the interior of the body 20 and also to permit the.

escape vof hot air 'from within the body.

Aconical baille 2G is supported within the body 20, intermediate itsends, by suitable supporting brackets 27 which yare similar in form, andattachment to the bracket 17.y T he conical baille 26 is constructed ofsheet metal i and provides a pocket opening downwardly, for receivingtherein the products of cornlouseV tion as they rise romthe burner of astove .mounted upon which the modifiedfform of radiator is Thelowerouter edge of lthe ,baffle 26 is spaced from the inner surface of thecylindrical body 20 to. permit the upward ypassageotx heated airthereabout. 1
